Abstract

Measuring the motorized spindle's motion error and the rotating parts' roundness are of great significance in machining. However, these two errors are usually mixed in measurement, and separating them is a big challenge. The three-probe method is suitable for on-machine measurement because it does not require the movement of the sensor during measurement. However, there is the problem of harmonic suppression in the three-probe method and harmonic suppression is closely related to the sensor installation angle. This study studied the harmonic suppression phenomenon and gave two performance indicators for angle optimization, optimized the angles in global scope, and gave the best recommended values for the sensor installation angles. A special fixture was designed for precise angle measurement and adjustment, and a cross-correlation analysis method was adopted. Simulations were then created to simulate theoretical errors, rounding errors, and angular uncertainties. Finally, experiments were conducted to verify the discussed errors and results.

分离主轴误差和圆度的传感器安装角全局优化

测量电主轴的运动误差和旋转零件的圆度在机械加工中具有重要意义。然而，这两种误差在测量中通常是混合的，分离它们是一个很大的挑战。三探头法适用于机器上的测量，因为它在测量过程中不需要传感器的运动。但三探头法存在谐波抑制问题，谐波抑制与传感器安装角度密切相关。本研究对谐波抑制现象进行了研究，并给出了角度优化的两个性能指标，在全局范围内对角度进行了优化，给出了传感器安装角度的最佳推荐值。设计了一种专用夹具进行精密角度测量和调整，并采用了互相关分析方法。然后创建模拟来模拟理论误差、舍入误差和角度不确定性。最后，通过实验验证了所讨论的误差和结果。
